Introduction

A new injection efficiency measurement system was recently developed and implement at Siam Photon Source (SPS). The system is used to calculate beam charge and efficiency at all detectors:electron gun, LBT, HBT, and storage ring. The system is composed of two oscilloscopes, voltmeter, and an analog to digital PXI module. The oscilloscopes are used to measure current from the gun, LBT, and booster. The voltmeter is used for current measurement in the storage ring and is logged into a server.The PXI module is the main controller of the system used for HBT. After a trigger signal reached the PXI, all the data is collected and calculated using a LabVIEW program.
